ITX Low Profile vs Tower ARGB
Tower design
The Thermalright AXP90-X53 is a low-profile cooler with a total height of 53mm. This compact design fits inside small ITX cases and HTPC builds where space is tight. It measures 94.5 by 95 by 53mm. The Thermalright Assassin X 120R SE is a standard single-tower cooler standing 148mm tall. Its dimensions are 120 by 71 by 148mm. This size requires a mid-tower or larger case. You must choose the AXP90-X53 for strict height limits. You should pick the Assassin X 120R SE if you have standard case clearance.
Fan size
The AXP90-X53 uses a 92mm fan, specifically the TL-9015 model. This fan is matched to the narrow fin stack of the low-profile design. The Assassin X 120R SE uses a larger 120mm fan, the TL-C12C-S. Larger fans generally move more air at lower speeds. The 120mm fan on the Assassin X provides higher maximum airflow of 66.17 CFM. The 92mm fan on the AXP90-X53 offers 42.58 CFM. You get better airflow potential with the larger 120mm fan on the Assassin X 120R SE.
Fan speed
The AXP90-X53 fan spins at a maximum of 2700 RPM. This higher speed helps compensate for the smaller 92mm fan diameter. It also helps move air through the dense, low-profile fin array. The Assassin X 120R SE fan runs at a lower maximum speed of 1550 RPM. This lower speed contributes to its quieter operation. The AXP90-X53 reaches a noise level of 22.4 dB at max speed. The Assassin X 120R SE reaches 25.6 dB. You get quieter operation from the Assassin X 120R SE due to its lower RPM.
Lighting
The Assassin X 120R SE includes ARGB lighting on its fan. You can sync these colorful effects with compatible motherboards. The fan is described as providing gorgeous light effects. The AXP90-X53 does not list any lighting features in its specifications. It is a functional cooler focused on heat dissipation in small cases. If you want visible RGB lighting in your build, the Assassin X 120R SE is the clear choice. The AXP90-X53 offers no lighting options.
Socket compatibility
Both coolers support a wide range of modern CPU sockets. The AXP90-X53 supports Intel LGA1150, 1151, 1155, 1156, 1200, 1700, and 1851. It also supports AMD AM4 and AM5. The Assassin X 120R SE supports the same Intel sockets and AMD AM4 and AM5. Both use AGHP technology for their four 6mm copper heat pipes. Both include necessary mounting hardware for these platforms. There is no difference in socket support between the two models. Both offer broad compatibility for current and previous generation CPUs.
Which Thermalright cooler fits your build
Small ITX case builders needing low height
The AXP90-X53 stands only 53mm tall. This compact profile allows installation in tight ITX chassis where larger coolers do not fit. The 92mm fan maintains a low 22.4dB noise level. You get efficient cooling without sacrificing case compatibility or RAM clearance in small form factor builds.
Users wanting ARGB lighting effects
The Assassin X 120 features ARGB lighting for visual customization. Its 120mm fan delivers 66.17 CFM of airflow. The single-tower design stands 148mm high. This cooler suits standard ATX cases where aesthetics matter. You receive both performance and visual appeal for your system build.
Standard ATX users prioritizing airflow
The Assassin X 120 uses a 120mm fan for superior air movement compared to the 92mm option. It provides 66.17 CFM of airflow. The 148mm height fits most mid-tower cases. This configuration offers robust cooling capacity for general desktop use where space is not restricted by small chassis limits.
